I have an 2xUART and 2xHiKey (1xDebian 1xAndroid) boards, but no idea on how to use the UART nor any idea what to expect after I connect to them.
The UART adapter is the one from 96Boards UART.
What I did till now:
- Plugged the UART boards in like described here 96Boards UART Userguide. I did not change any jumper settings.
dmesg | grep ttyto identify the ttyUSB port. I get the following message
usb 2-1.2: FTDI USB Serial Device converter now attached to ttyUSB0. Therefor it is
screen /dev/ttyUSB0to connect to the device, but I always get
[screen is terminating]
What do I do wrong?
What would be the expected output of the UART connection?
